GILTI, BEAT, and FDII Explained: Key U.S. International Tax Changes for Multinationals
March 13, 2026
Article Overview:
The international tax landscape is undergoing a significant transformation. With the passage of the One Big Beautiful Bill Act (OBBBA), the Tax Cuts and Jobs Act (TCJA) framework governing GILTI, BEAT, and FDII has been substantially revised. These changes alter how multinational enterprises calculate their global effective tax rate and structure cross-border operations.
I. What Are GILTI, BEAT, and FDII?
Since 2017, the trio of GILTI, BEAT, and FDII has served as the backbone of the U.S. international tax regime. Originally enacted under the Tax Cuts and Jobs Act (TCJA), these provisions were designed to balance two competing objectives: discouraging U.S. companies from shifting profits to low-tax jurisdictions while incentivizing them to keep high-value assets and services within the United States.
However, as we enter 2026, the "wait and see" period has ended. The One Big Beautiful Bill Act (OBBBA) has introduced the most significant modifications to these rules since their inception. For multinational enterprises (MNEs), these changes represent more than just a nomenclature shift; they alter the fundamental mathematics of global effective tax rates (ETRs). Navigating this new reality requires a comprehensive international tax analysis to avoid the traps of the prior law and capitalize on the new "permanency" of these provisions.
II. How GILTI Changes Under the OBBB (Net CFC Tested Income)
Perhaps the most dramatic change is the rebranding and restructuring of the Global Intangible Low-Taxed Income (GILTI) regime. As of 2026, GILTI is officially renamed Net CFC Tested Income (NCTI).
1. The Elimination of the QBAI "Tangible Return."
Under the prior law (2018–2025), GILTI was calculated by subtracting a "routine" 10% return on tangible assets—known as Qualified Business Asset Investment (QBAI)—from a company's total foreign profits. The goal was to only tax "intangible" or "supernormal" profits.
The Change: The OBBBA eliminates the QBAI deduction.
The Impact: Every dollar of active foreign income earned by a Controlled Foreign Corporation (CFC) is now subject to U.S. tax, regardless of how many factories or pieces of machinery the company owns abroad. This effectively increases the tax base for companies with heavy tangible operations.
2. New Deduction Rates and Effective Tax Rates (ETR)
Prior Law: MNEs were allowed a 50% Section 250 deduction on GILTI, resulting in a 10.5% effective tax rate. This was scheduled to drop to 37.5% in 2026, raising the rate to 13.125%.
The New Law: The OBBBA sets the deduction permanently at 40%.
The Result: The new headline effective tax rate for NCTI is 12.6% (assuming the 21% corporate rate).
3. Relief on Foreign Tax Credits (FTC)
To soften the blow of the QBAI removal, the new law reduces the "haircut" on foreign tax credits from 20% down to 10%. This means you can now credit 90% of the taxes paid to foreign governments against your U.S. NCTI liability, making it easier to reach a "zero-tax" position if your foreign rate is at least 14%.
III. FDII Becomes FDDEI: Changes to the Export Incentive
The counterpart to GILTI was always the Foreign-Derived Intangible Income (FDII) deduction, designed to give U.S. exporters a tax break similar to what they would get by moving operations abroad. Under the OBBBA, FDII is renamed Foreign-Derived Deduction Eligible Income (FDDEI).
TCJA Rules (2018–2025): Domestic corporations could take a 37.5% deduction on income derived from serving foreign markets, leading to a 13.125% effective rate.
OBBB Framework (2026+): The OBBBA sets the deduction at 33.34%, resulting in a permanent 14% effective tax rate.
Narrowed Scope: The legislation excludes gains from the sale of intangible or depreciable property from the calculation, focusing the benefit strictly on operational export income rather than one-time asset dispositions.
IV. BEAT: Preventing Base Erosion in a Pillar Two World
The Base Erosion and Anti-Abuse Tax (BEAT) functions as a minimum tax for massive corporations (over $500 million in revenue) that make significant payments to foreign affiliates.
The Rate Lock: BEAT was scheduled to jump to 12.5% in 2026. The OBBBA instead "permanently" locks the rate at 10.5% (11.5% for banks and securities dealers).
Treatment of Tax Credits: One of the most favorable changes is that certain U.S. tax credits—which were previously scheduled to be excluded from the BEAT calculation (making the tax more expensive)—are now permanently allowed as offsets.
V. Key Comparisons: TCJA (2018–2025) vs. OBBB Framework (2026)
The following table summarizes the shift for a typical U.S. C-Corporation:
Provision
TCJA Rules (2018–2025)
OBBB Framework (2026+)
GILTI/NCTI Deduction
50% deduction (10.5% rate)
40% deduction (12.6% rate)
QBAI Exclusion
10% of tangible assets
None (Eliminated)
FTC Haircut
20% (80% creditable)
10% (90% creditable)
FDII/FDDEI Rate
13.125% ETR
14% ETR
BEAT Rate
10%
10.5% (11.5% for banks & securities dealers)
VI. Understanding the NCTI “Crossover Rate”
For tax leaders, the "Crossover Rate" is the threshold at which foreign taxes completely offset U.S. tax on offshore income.
The Math: Because of the lower 10% FTC haircut and the 40% NCTI deduction, a U.S. corporation generally owes zero residual U.S. tax if its foreign subsidiaries pay an effective rate of at least 14%.
Simplification: In an effort to align with the global Pillar Two minimum of 15%, the U.S. has effectively raised its "minimum tax" floor.
VII. Planning for the "One Big Beautiful Bill" Implementation
MNEs cannot afford to wait until they file their 2026 returns to understand these impacts. Immediate action items include:
Modeling the QBAI Removal: If your foreign subsidiaries own high-value manufacturing plants, your NCTI inclusion will likely jump significantly.
Evaluating FDDEI Benefits: Assess whether your domestic operations still qualify under the narrowed definitions of export income.
Expense Allocation Review: The new law limits the allocation of interest and R&D expenses against the NCTI basket, which may actually increase your ability to utilize foreign tax credits.
Supply Chain Reassessment: Structures that relied on holding tangible assets abroad for the 10% QBAI return may no longer be tax-efficient.
VIII. Conclusion: Adapting to the New Permanent Reality
The overhaul of GILTI, BEAT, and FDII signals a shift away from a system that favored tangible offshore assets toward a simpler, broader income-based model. By making these rates permanent, the OBBBA provides a level of certainty that has been missing from international tax planning for years.
However, certainty does not mean simplicity. The interplay between these provisions and global developments like Pillar Two ensures that the compliance burden remains high. Success in this new era requires moving beyond traditional structures and toward integrated tax and operational strategies. The businesses that thrive will be those that use these rules not just as a compliance hurdle, but as a roadmap for global growth.
